Comment: UPD is comprised of the Universal OPC Server (UOS) for Serial and TCP/IP Devices and the PAXD.PRO device profile. The UPD mnemonic is used to identify this unique combination. UOS will also support many other serial or TCP/IP device profiles. Please refer to our web site for the current list.
UOS is a stand-alone OPC Server that can be used with any OPC compliant Client such as Intellution’s FIX® or FIX Dynamics® or OA’s Enterprise Automation software. UOS has many advanced features like: DataView, DataScope, Serial and TCP/IP communications support, and multiple "different" device support. Please refer to our web site for more information on UOS capabilities.

Introduction
This document provides general information on the device commands supported by UOS and the PAXD.PRO profile. If you have installed UOS, you should also review the sections titled About the I/O Driver, How Do I…, Setting up The I/O Driver, and Using the PowerTool in the UOS electronic documentation. To get there, click on Help and Help Topics on the PowerTool menu bar. The PowerTool is a client application with a graphical user interface that accesses the UOS OPC Server and lets you view and modify communications channel, device, and datablock properties.
 
Device Commands Supported
The device READ/WRITE commands supported are shown in Table 1. They are described in reference to the profile command group that contains them. A "profile command group" is a group of related commands. Usually it consists of an I/O Device READ/WRITE command pair. However the command group can contain only a device READ command, only a device WRITE command, or more than one device READ/WRITE pair. This depends on the protocol of the I/O Device to which the command is directed.
